Phoenix Arizona Residential Manual “D” Duct Design

Residential Manual “D” Duct Design

The Manual D is a complete schematic drawing of the duct system including locations and sizes of trunk-lines, branch ducts, outlet registers, and inlet grilles.

Remember, before any Manual D can be performed, you’ll first need the information calculated from Manual J software which will calculate all the factors and provide the sensible and latent capacity required to heat and cool the home. This capacity is then used to match a heating and cooling system which will produce the same capacity within tolerance. This very important match-up is completed by utilizing the Manual S requirements. Once the equipment selection is completed, the duct work can now be designed using specific factors given to us by the equipment manufacture’s fan rating and pressure drop charts in which we can apply to your new duct design using Manual D requirements.

Getting a complete Manual-D done on your property plans is the best way to ensure that your heating and cooling system will deliver maximum comfort at high efficiency. It is the most recognized way to ensure that your system will be able to deliver the correct amount of air to each room.

Service second to none!
I was lucky enough to have met Josh and got his business card about 48hrs prior to my AC going out. It was the Thursday before Labor Day and he took my call, he dropped everything to hop on my 110* roof to get my AC back up and running practically immediately, but it stopped working again and it took me until about 4pm on Friday before Labor Day Weekend when I gave Josh the green light to replace the unit (mind you the house got 95* at night) and wouldn't you know it - Josh moved mountains for me and had a crane out front by 8am Sat morning to haul the new AC unit on my roof. He sent me before and after photos, was always in contact, and checked in often to make sure everything was ok. The whole experience was very smooth and I will always recommend and use the very professional JL Finley Construction for any AC/Heater needs.

1st rate quality and service, I had a new rooftop HVAC unit and air handler installed by JL Finley Construction along with a water softener and a RO water system, and I am 100% pleased. I got 3 quotes and Josh was very fairly priced for the amount and quality of work that he performed. Always on time and kept me up to date on all the progress of the work being done. Answered all my questions and discussed all the options that were available to me plus the work on the job site was extremely neat and tidy.

Excellent experience! I recently had a new rooftop HVAC unit installed by JL Finley Construction. Josh was very professional and able to provide clear explanations of several options appropriate to my situation. Once the unit was selected, the project was completed in an efficient and professional manner. Josh also offered to absorb the additional cost of a larger crane, which was required to place the unit (and had not been included in the initial estimate). His attention to detail, knowledge, experience, and respectful manner were much appreciated.

I received Josh’s info through a long line referrals. Customer service is clearly important with this company. I had them install a new AC unit and re-roof at the same time. Top notch installation and attention to details.

I recently purchased a condo and hired JL Finley to service my AC system. He was very detailed in his explanation, as he was when he completed the work that was needed! It means everything to find a contractor who is honest and does the work needed for a fair price! Mr. Finley did just that! He explained everything in a way I could understand! Thank you. . .I couldn't be happier!
